The entire contents of the above-referencedapplications are expressly incorporated herein by reference for allpurposes.

FIELD OF THE APPLICATION

The present application relates to network communication and informationtransmission. Particularly, the application relates to a method andsystem for providing tourist assistance and guided navigation of atourist spot by transmitting metadata across a communication network.

BACKGROUND OF THE INVENTION

‘Information’ has become an absolutely essential part of every humanactivity. Over the time several protocols have been developed thatfacilitate sharing of information with information tourists fordifferent applications.

Public exposure of the useful information related to the any strategiclocation such as a tourist spot, not only helps the tourist to navigateproperly through out the said location but also provides the generalknowledge about the particular location. The strategic location mayinclude but not limited to a tourist spot, a museum, an article in themuseum, a fort, an amusement park or a conference venue.

In the current scenario, audio, visual or audio-visual display ofinformation is the most common means for information dissemination insuch tourist spot. Wherein the tourist is always dependent on limitedinformation, played or displayed related to that particular strategiclocation. Since there is no such technical provision where the touristis enabled to receive detailed metadata about the particular strategiclocation along with the associated web based information on theirpersonal communication device.

Since, the information age today is well pillared on the considerablydeveloped communication protocols. The metadata transmission over aparticular communication network having subscribed by plurality oftourists have been proved to be the best known method for informationdissemination in an environment described above.

The metadata specific frequency selection for transmitting the metadataover a particular communication network has been confronted as one ofthe major technological challenge.

The existing communication modes being used such as internet protocol(IP), Wi-Fi, Bluetooth, ZigBee etc. However, the said communicationmodes require a special hardware support and setup for aninfrastructure.

Hence it becomes inevitable to formulate a method and system which shalltransmit metadata related to the particular strategic location over thebeyond audible frequency signal on tourist's personal communicationdevices. The transmitted metadata shall provide tourist assistance andguided navigation to the tourist through out the particular tourist spotand help increasing their knowledge about it.

Lots of efforts have been made to develop various approaches to attemptthe said problem; most of the generic methods do not utilize specificfrequency for metadata transmission. Most of the prior arts do notenable the tourists to access the metadata related to the particulartourist spot on their personal communication devices for guidednavigation through out the particular tourist spot.

Thus it becomes extremely necessary to provide a method and system forproviding tourist assistance and guided navigation of a tourist spot bytransmitting metadata transmission across the communication networkwhich can utilize the beyond audible frequency signal, as well asexisting hardware setup of a mobile communication device.

However, the existing methods and systems particularly are not capableof providing a solution for tourist assistance and guided navigation ofa tourist spot by transmitting metadata across the communication networkover the beyond audible frequency signal. Some of above mentionedmethods known to us are as follows:

U.S. Pat. No. 6,790,182 to Eck at al. teaches an ultrasound imagingsystem for imaging ultrasound scatterers, comprising a probe fortransmitting ultrasound waves and detecting ultrasound echoes reflectedby said ultrasound scatterers. The patent does not teach about metadatatransmission across a communication network, over a beyond audiblefrequency signal.

U.S. Pat. No. 5,854,589 to How et al. teaches a magnetic/acoustictransducer, which can be used in security/smart tag applications. Thepatent does not teach about metadata transmission across a communicationnetwork, over a beyond audible frequency signal.

US20050171429 to Mathew et al. teaches a system and method for animproved image acquisition rate in an ultrasound imaging system. Thepatent application does not teach about metadata transmission across acommunication network, over a beyond audible frequency signal.

WO2006119764 to Blaabjerg at al. teaches a system for determining theposition of an object such as an array of measuring microphones relativeto a fixed station of the system. The patent application does not teachabout metadata transmission across a communication network, over abeyond audible frequency signal.

Filonenko et al. in “Investigating Ultrasonic Positioning on MobilePhones” evaluates the innate ability of mobile phone speakers to produceultrasound and the possible uses of this ability for accurate indoorpositioning.

Simonite in “Bringing Cell-Phone Location-Sensing Indoors” teaches smallbeacons, fixed to a store's ceiling beam out an ultrasound signal at afrequency that can be picked up by a cell phone's microphone but not byhuman ears.

Richard et al. in “The Ultrasound Smartphone” teaches an ultrasoundsmartphone, coupled with a USB-based probe, enabling a compact, mobilecomputational platform and a medical imaging device that fits in thepalm of a hand.

Mobisante Inc. in “Portable ultrasound scanner with a Smartphone”teaches a diagnostic for high-quality images at low cost based on thetraditional ultrasound technology.

Suilivan in “Zoosh: An Alternative to Google Wallet & NFC” teaches NearField Communication (NFC) using the simple speaker and microphone foundin mobile devices.

The above mentioned prior arts fail to disclose an efficient method andsystem for metadata transmission across the communication network. Theprior art also fail to disclose about a method and system which couldutilize the beyond audible frequency signal as well as existing hardwaresetup of a mobile communication device for metadata transmission acrossa communication network for providing tourists with guided navigation.

Thus, in the light of the above mentioned background art, it is evidentthat, there is a long felt need for such a solution that can provide aneffective method and system for providing tourist assistance and guidednavigation of a tourist spot by transmitting metadata across thecommunication network over the beyond audible frequency signal utilizingexisting hardware setup of a mobile communication device.
